No :)

We need to add some new bindings to do cross-thread back to the  
UIThread a little better.  This is being worked on today.

As for if you do want to do CocoaTouch things on a async thread, you  
need to create and release a NSAutoreleasePool, and the functionality  
for this will be in the next release.
